In 2026, it is almost always better to transfer American Express Membership Rewards points to an airline partner rather than using them to book travel directly through the Amex Travel portal. When you book through the portal, your points typically have a fixed value of 1 cent per point. However, by transferring to partners like British Airways (Avios), Virgin Atlantic, or Air France-KLM (Flying Blue), you can often achieve values of 2 to 4 cents per point, or even higher when booking international Business or First Class "sweet spots." For example, a Business Class flight to Europe might cost 300,000 points on the portal but only 60,000 to 80,000 points when transferred to a partner during a 25% transfer bonus window, which are common in 2026. The only time the portal is "better" is if you find a very cheap economy fare and don't want to deal with the complexities of award availability, but for anyone looking to maximize the "math" of their rewards, transferring to airlines is the gold standard.
